<a name="idm37016"></a><h2>Description</h2>
<p>This macro is not a configuration macro and this library will generate a compile-time error if users try to define it directly. This library will automatically define this macro when users do not define  <code class="computeroutput"><a class="link" href="BOOST_CONTRACT_DYN_LINK.html" title="Macro BOOST_CONTRACT_DYN_LINK">BOOST_CONTRACT_DYN_LINK</a></code> (or <code class="computeroutput">BOOST_ALL_DYN_LINK</code>) and  <code class="computeroutput"><a class="link" href="BOOST_CONTRACT_STATIC_LINK.html" title="Macro BOOST_CONTRACT_STATIC_LINK">BOOST_CONTRACT_STATIC_LINK</a></code>. When used as a header-only library, this library code does not have to be compiled separately from user code, this library headers are simply included and compiled as part of the user program.</p>

<tr><td align="left" valign="top"><p>This library is not guaranteed to always work correctly at run-time when this macro is defined (define  <code class="computeroutput"><a class="link" href="BOOST_CONTRACT_DYN_LINK.html" title="Macro BOOST_CONTRACT_DYN_LINK">BOOST_CONTRACT_DYN_LINK</a></code> or <code class="computeroutput">BOOST_ALL_DYN_LINK</code> instead). However, this macro can be defined and this library can be safely used as a header-only library for user code that checks contracts in a single program unit (e.g., a single program with only statically linked libraries).</p></td></tr>
